Most AI writing tools sound great until you actually try to use them in the middle of a real scene.

The pitch is easy to understand. Faster drafts. More ideas. Fewer moments where you’re sitting there, stuck on a paragraph that should not be taking this long.

And honestly, that part is appealing. You generate a bit of text, and at first it can feel like the tool just bailed you out. The scene moves again. The sentence you were stuck on has somewhere to go. Maybe the output even sounds pretty good on the first read.

Then you come back to it later and start noticing little things. The prose is fine, but not quite yours. The paragraph works, but it has that smooth, slightly empty feeling a lot of AI writing has. It moved the scene forward, but maybe not in the direction you would have chosen if you’d sat with it a little longer.

That’s been my main hesitation with AI writing tools in general. They can help, but they can also make it easier to drift away from your own voice without realizing it.

Sudowrite is different from a lot of the tools I’ve tried because it’s built specifically around fiction. That doesn’t automatically make it good, but it does mean the tool is at least trying to solve the right problem.

I’ve been using it for a while now inside actual fiction projects, not just running a few prompts to see what happens. And that’s really the only way to judge something like this.

Does it help you keep writing when you’re stuck?

Does it give you useful options without taking over the scene?

Does it still feel like your book when you’re done?

That’s what I wanted to figure out.

Quick note: I should mention that Kindlepreneur's special partner link for Sudowrite will give you 200k bonus credits if you use it to sign up and decide to upgrade. We'll receive a small commission, but there's no extra cost to you.

What it’s like to write with Sudowrite

A common fear among writers is that AI will eventually churn out books without us. Press a button, get a finished novel.

That’s not where we are, and frankly, I doubt we’ll get there anytime soon. Even if the technology could produce a coherent story in seconds, I believe readers would still crave the spark that comes from a human imagination.

Right now, AI writing tools are more like productivity sidekicks than replacements. They can handle some of the smaller, more repetitive parts of writing, which frees you up to focus on the bigger decisions like character, structure, and story direction.

The best analogy I’ve heard is that AI is to writing what calculators are to math. It helps with the tedious parts, but it doesn’t replace the thinking.

In practice, that’s where Sudowrite tends to be the most useful, especially in those moments where a sentence isn’t quite working, a paragraph feels flat, or you know what needs to happen next but can’t quite get there. Instead of replacing the writing, it gives you a few options to work from, which can make it easier to keep moving.

That’s how I’ve ended up using it over time. Not as something that writes for me, but as something that helps reduce the mental load. Writing fiction can be mentally exhausting, especially when you’re deep into a scene and trying to keep everything consistent, so having something that can help you push through those sticking points makes a noticeable difference over longer writing sessions.

It doesn’t replace the writing process, but it can make it easier to sustain.

What Sudowrite is (and how it works)

Sudowrite is an AI writing and editing tool, but that description doesn’t really set it apart on its own. There are plenty of AI tools out there, and most of them can generate text in one form or another.

Where Sudowrite is different is that it’s built specifically for fiction authors.

It includes a range of features designed to support the writing process, from the Story Bible, which helps you organize characters, settings, and other elements of your novel in a way the AI can reference, to brainstorming tools, rewrite options, and a story-aware Chat feature that can help you think through or edit parts of your project.

In that sense, it’s less of a single-purpose tool and more of a collection of tools that are all aimed at helping you move a story forward.

It’s also fairly feature-rich, which is part of its appeal, but it can take some time to understand how everything fits together.

How Sudowrite fits into the writing process

There are a lot of features inside Sudowrite, and it can feel like a lot at first. It isn’t really a single-purpose tool so much as a collection of tools that help at different stages of the writing process.

Once you spend some time with it, though, those features start to fall into a few clear categories, depending on what you’re trying to do.

Muse

By far the most important flagship feature that Sudowrite offers is the Muse model, a Large Language Model (LLM) that has been specifically designed and fine-tuned for creative writing.

Your mileage may vary, but from my own experience with it, it's the best model I've ever worked with for that specific purpose.

The Muse model is now publicly available and powers a lot of the core writing features, including Draft, Expand, and Guided Write.

The Muse model has an intuitive understanding of a scene like no other AI I've worked with, including an understanding of blocking, good dialogue, witty humor, and just overall strong prose. It’s probably the main reason why Sudowrite stands out compared to other AI tools.

They’ve also been updating the underlying models fairly regularly, so the output isn’t static. Newer models get added over time, and the overall quality has improved because of that.

The Writing Tools

First, let’s start with what most people are probably interested in: the writing tools. These are the tools that are best for longer-form writing.

If you’re hoping to use Sudowrite to help with a first draft, this is where most of that work happens. And if you’re already writing in something like Scrivener, there’s now a way to import an entire project directly into Sudowrite, including the folder structure. That makes it a lot easier to move an existing draft into this workflow without rebuilding everything from scratch.

Draft is a feature where the AI can take a detailed summary of your chapter, usually in the form of 10–20 beats, and write out a full draft. Personally, I’ve found this to be a bit hit or miss, and I tend to prefer writing in smaller sections, but it can be useful if you want a quick draft to work from.

Guided Write and Auto Write are the tools used to continue writing each section of your story. With Guided Write, you can add a sentence or two about what happens next, and Sudowrite will continue from there based on your direction. The Write tool can generate completions in different lengths, and Sudowrite’s docs describe the Write button as generating anywhere from about 50 to 2,000 words depending on your settings. Auto Write works similarly, but without the guidance, so you can see where the model takes the scene. Combined with the Muse model, these are the features I use most often when drafting.

There are also smaller tools like Tone Shift, which allows you to adjust the tone of your writing, and Expand, which lets you take a shorter paragraph and build it out with more detail or dialogue. Expand is one of the features I use the most, especially when a scene feels too compressed.

Revision Tools

Revision is one of the areas where AI tends to perform well, and that shows up clearly in Sudowrite’s revision tools. These are the features I tend to use once a draft is already in decent shape, or after importing a manuscript from elsewhere.

The Rewrite feature is one of the most useful. It allows you to rephrase text, shorten it, make it more descriptive, or shift it toward things like showing instead of telling, adding more inner conflict, or increasing intensity. You can also customize it with your own prompts.

One of the ways I use this most is with “Show, don’t tell.” AI-generated text often leans toward telling, so being able to quickly select those sections and adjust them is helpful.

The Describe tool is another one I use often. Description is something I personally struggle with, and Sudowrite can take a section and expand it using multiple senses, along with metaphors. It’s a useful way to add depth without having to come up with everything from scratch. There’s also a simple color highlighting system now, which makes it easier to track different threads or flag sections you want to come back to later.

Brainstorming Tools

This is one area where Sudowrite really stands out. There are a number of brainstorming tools built into the platform that can generate lists of ideas across different categories.

These include things like dialogue, characters, worldbuilding, plot points, names, places, objects, and descriptions, along with custom prompts if you want to generate something more specific.

In practice, I don’t usually take these outputs exactly as they are. Instead, I use them to get ideas moving. Sometimes a single suggestion is enough to spark something better, or combine with another idea into something more usable.

Plugins

Plugins were introduced as a way to add more flexibility to Sudowrite. While you still can’t directly modify the core prompts, you can create your own plugins or use ones created by the community for specific tasks.

Some of these plugins are genuinely useful, and it’s interesting to see how other users are extending the tool in ways that go beyond the default features.

Other Tools

Beyond the core writing, editing, and brainstorming features, there are a number of smaller tools that can be useful depending on how you work.

The Visualize feature allows you to generate images based on parts of your manuscript. It’s still more of a creative extra than something I rely on heavily, but it has really improved. It handles multiple characters better now and can pull from your Story Bible, which makes the outputs more usable than they used to be.

The Shrink Ray is a more practical feature. It takes everything in your current document and generates loglines, a blurb, a synopsis, and an outline, which can be useful for stepping back and seeing the bigger picture.

The Twist feature is another one I like, since coming up with good plot twists can be difficult. You provide a summary of your story, and it generates possible twists to consider.

There are also smaller features like the Poem tool, different visual themes, and the Canvas, which acts as a sort of virtual corkboard for organizing notes.

Story Bible

The Story Bible is a central part of how Sudowrite works when you’re writing a longer project. It allows you to store information about your characters, worldbuilding, and story structure in a way that the AI can reference as it generates text.

It includes sections for things like a braindump of your ideas, genre, style, synopsis, characters, worldbuilding, and outline. You can input as much or as little detail as you want, and the more information you provide, the more consistent the AI tends to be when generating content.

This is one of the features I find myself using the most, especially when working on a longer manuscript, because it helps keep everything aligned as the project grows. The more useful thing to know is that Story Bible rewards specificity. Sudowrite’s docs recommend putting plenty of detail into the Braindump, and the Outline section has no word limit, so you can go deeper when a project needs it.

Mobile app

One thing that didn’t exist when I first started using Sudowrite is a mobile app. There’s now an iOS and Android version, though it’s more of a companion app than a full replacement for the web app. Sudowrite says familiar features like Write and Rewrite are available, but other features are not; the mobile app is more focused on Smart Dictation, Smart Dictation Enhancement, and Chat.

It’s not something I use all the time, but it’s useful if you want to capture ideas without being at your desk.

Once you get a sense of how you’d actually use something like this, the next question is usually whether it’s worth paying for, and how the pricing is structured.

What Sudowrite costs

Sudowrite has three main pricing tiers, and you can either pay monthly or get a discount by paying annually. All plans currently include access to all of Sudowrite’s features; the main difference is how many credits you get each month and whether those credits expire.

The Hobby & Student plan starts at $19 per month (or $10 per month when billed annually) and includes 225,000 credits per month. The Professional plan is $29 per month (or $22 annually) and increases that to 1,000,000 credits, while the Max plan costs $59 per month (or $44 annually) and includes 2,000,000 credits.

Compared to other AI writing tools, that pricing lands somewhere in the middle. It’s not the cheapest option available, especially compared to tools like Novelcrafter or RaptorWrite, but it tends to offer more flexibility for fiction writing than general-purpose tools like Jasper or CopyAI.

One thing to keep in mind is that Sudowrite uses a credit system. Each time you use an AI feature, it consumes credits. Sudowrite says credit usage depends on the complexity of the task, including the number of words read, the number of words written, and the AI model being used. So there isn’t a clean one-credit-to-one-word conversion, and how far your plan goes depends a lot on how you use the tool.

One thing to be aware of with any AI tool is that models change over time. Sudowrite tends to keep older models available longer than most platforms, which can be helpful if you’ve built a workflow around a specific one.

In my experience, the middle Professional plan strikes a reasonable balance for most writers. It gives you enough credits to use the tool regularly without feeling too limited. Heavier users may find the Max plan worth it, especially since that is the tier Sudowrite currently lists with rollover credits.

Sudowrite doesn’t offer a permanent free plan, but they do provide a free trial with no credit card required.

At the time of writing, Kindlepreneur’s partner link includes 200,000 bonus credits. Since partner bonuses can change, I’d double-check the current offer before publishing.

Where Sudowrite works well

Now that I’ve spent a fair amount of time using Sudowrite, there are a few areas where it consistently stands out to me.

The Muse model is easily the biggest one. This is my favorite feature, and the one that saves the most time. From my experience, it’s the best large language model I’ve used for creative writing so far, and it’s likely to keep improving.

The Expand feature is another standout. Alongside Guided Write, it’s one of the most reliable ways to generate additional content that you can then shape and refine. It’s especially useful when a section feels too compressed and needs to be built out.

The brainstorming tools are also a major strength. There’s a lot here, across multiple categories, and I’ve found that even when I don’t use the outputs directly, they help get ideas moving. It’s hard to run into a situation where you’re completely stuck.

The outlining feature is something I’ve come to rely on as well. There’s something very satisfying about entering a story treatment and getting a solid outline back, and I expect I’ll continue using AI as part of that process going forward.

The Rewrite tool is another one I use frequently. Being able to target specific issues, like “show, don’t tell,” and adjust passages quickly is a big advantage, especially since both human writers and AI tend to lean too much on telling.

The Twist feature is similar in that it helps with a specific creative challenge. Coming up with strong twists can be difficult, and this tool has generated several ideas that I’ve been able to use or adapt.

Finally, the overall design of the tool is fairly clean compared to many other AI platforms. It feels like there’s an effort to keep things simple and focused, which makes it easier to work with over longer sessions.

Where it starts to fall short

Despite everything Sudowrite does well, there are a few areas where it could be improved.

The pricing structure is one of them. Because it relies on a credit system, it’s possible to go through credits fairly quickly, especially if you’re using more advanced models. That can make it harder to predict ongoing costs.

Another limitation is the lack of API integration. Some other tools allow you to connect to third-party providers, which can make it easier to test newer models or reduce costs. With Sudowrite, you’re limited to what they make available, so you have less flexibility in that area.

I also found the Canvas feature to be less useful than I expected. In its current form, it can feel a bit unstructured, especially when trying to organize things like characters or worldbuilding. Personally, I would prefer something closer to the Story Bible approach, where those elements are more clearly defined and easier to manage, although that may come down to personal preference.

The mobile app is also worth thinking of as a companion app rather than a full version of Sudowrite on your phone. That isn’t necessarily a bad thing, but if you expect the same workflow you get in the browser, you may run into some limits.

That said, the Sudowrite team has been very responsive to feedback and continues to release updates. In one case, a feature I had specifically wanted — the ability to generate a single card instead of multiple — had already been added by the time I was working on the first draft of this review.

Who Sudowrite is best suited for

For the right type of writer, Sudowrite can be extremely useful.

If you’re someone who enjoys drafting but occasionally gets stuck, this is where Sudowrite tends to shine. The ability to generate a continuation, expand a scene, or get a few variations of a sentence can be enough to keep momentum going instead of stalling out.

It’s also a strong fit for writers who like to explore ideas as they go. The brainstorming tools, the Twist feature, and even something like Rewrite can open up directions you might not have considered. Even if you don’t use the outputs directly, they can help you get to a better version of what you were already working on.

Writers who struggle with specific parts of the process, like description, outlining, or rewriting “telling” passages, will probably get a lot of value from it as well. Those are areas where the tool is particularly helpful, especially when used selectively instead of relying on it for everything.

At the same time, I don’t think this is a great fit if you’re looking for something to write a complete novel for you. While features like Draft exist, the results are inconsistent enough that you’ll still need to do a significant amount of editing. In most cases, it works better as a tool you write alongside, not something you hand the work over to.

The credit system is another factor to consider. If you plan on using AI heavily for large sections of text, you’ll go through credits quickly, and that can add up. It’s much easier to manage when you’re using it in smaller, targeted ways.

Ultimately, I’ve found that Sudowrite works best when it’s treated as a support tool rather than a replacement for the writing process. When you use it to fill gaps, explore options, or get unstuck, it can make the process smoother and less mentally draining. When you try to rely on it too heavily, the results tend to flatten out and require more work to bring back to life.

I'm a big fan of it, so I do highly recommend it, but as with most things, your mileage may vary.

A quick note from Kevin

One quick note from me before you decide whether to try Sudowrite.

AI writing tools are hard to judge from a distance. You can compare features, look at pricing, and read through a few sample outputs, but none of that really tells you what it feels like to use the tool while you’re in the middle of an actual story.

That’s why I wanted Jason’s take on this one.

He’s spent more time inside Sudowrite than I have, and more importantly, he’s used it the way a fiction writer would actually use it. Not as a toy. Not as a quick “let’s see what happens” experiment. As something sitting beside him while he works through real scenes.

That matters because Sudowrite is not the kind of tool where the feature list tells the whole story. Some of the value is in the small stuff. Getting a stuck paragraph moving. Expanding a compressed moment. Seeing a few possible directions when your brain is out of ideas.

I still don’t think any AI tool should take over the writing for you. And if you use it too heavily, you can absolutely end up with prose that feels flatter than what you started with.

But used carefully, Sudowrite can be helpful. Especially if you’re a fiction writer who wants AI support without using something that feels like it was built for marketing copy first and novels second.

If you’re curious how it might fit into your own process, the best thing you can do is try it on something you’re already working on and see how it behaves. We have a partner link that includes 200,000 bonus credits at the time I’m writing this, which should be more than enough to get a feel for how the tool works before committing to anything long-term.

If you want to see Jason walk through the tool on video, I’ve embedded his full walkthrough below.
